PAPER FILE.

SPECIFICATION forming part of Letters Patent NO. 405,596, dated June 18,1889.

Application filed February 15, 1839. Serial No. 300,018. (No model.)

To all whom it may concern:

Be it known that I, BERNHARD Pnrsonn, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, a citizen of the German Empire,have invented certain new. and useful Improvements in Paper-Files, ofwhich the following is a specification.

This invention relates to an improved paper-file which has the advantagethat it can be operated by one hand only, without requiring the otherhand for removing the springclamp that holds the papers in position; andthe invention consists of a paper-file composed of a base plate orframe, a hinged and springactuated supporting-plate for the papers to befiled, a clamping device hinged to the baseplate and bent so as toext-end over the head of the supporting-plate, and arms attached to thesupporting-plate and adapted to engage the clamp, so as to oscillate itwhen the supporting-plate is depressed.

The invention consists, further, of certaindetails of construction bywhich the working of the parts composing the paper-file is rendered moreeffective, as will be fully described hereinafter, and finally pointedout in the claims.

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved paper-file. Fig. 2 is a vertical longitudinal section of thesame; and Fig. 3 is a modified construction of my improvedpaperfile,showin g it as suspended from the wall.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the base plate or frame of myimproved paper-file, which frame is made either of wood, cast metal,wire, or other suitable material. To one end f the base plate or frameAis hinged a sup porting-plate B, which is acted upon at its oppositeend by a spiral or other cushioning spring b,that is interposed betweenthe baseplate and hinged plate B. To the head of the base-plate A ishinged a clamping device 0, which is made either of wire, sheet metal,or other suitable material, and bent in such a manner that its upperpart 0' extendsover the head of the supporting-plate B, as shown in Fig.1.

The shanks of the clamping device 0 are engaged by perforated arms D,attached to the under side of the head of the plate B. The shank orshanks of the clamping device C are bent forward at their lower parts,said bent parts being acted upon by the arms D when the plate Bisdepressed. The pressure of the arms D on the bent lower portion (1 ofthe shanks of the clamp 0 produces the oscillating of the clamp O awayfrom the head of the supporting-plate B, as shown in dotted lines inFig. 2, so as to clear the latter entirely and permit the paper to beplaced on the same. The baseframe A may also be provided with asuspension-eye a for suspending it from a hook 011 the wall, as shown.in. Fig. 3, in which case the spring which operates the clamp andsupporting-plate is made integral with the base-frame.

The paper-file is operated as follows: By depressing thesupporting-plate B the head of the same recedes from the transversefront edge of the clamp C until the arms I) engage the forwardly-bentlower parts d of the clamp, when the upper part C will be quickly movedaway from the head of the plate B. On relaxing the pressure on thesupporting-plate the same is raised by its cushioning-spring l) andpressed against the transverse upper part of the clamp as the same isreturned to its normal position above the head of the supporting-plate.For placing a paper on the file, all that is necessary is to place itwith its edge over the transverse upper part of the clamp and press thesupporting-plate down. The paper will readily pass below the clamp andbe retained by the same on releasing the plate B, when it and the clampare return ed to their former position. Only one hand is necessary foroperating the file, instead of two, as heretofore, in files for similarpurposes. By making the cushioning-spring of the supporting-plate ofsufficient strength the file can also be used as a memorandum-pad, onwhich the paper is held in inclined position for writing. By suspendingit from the wall the file can be used as a convenient spring-clip forfiling bill and similar papers, while, when made on a larger scale, itcan be used as a writing-desk, and when made on a very small scale itcan be used as a book-mark and as a clamping device for retaining theleaves of a book While reading.

Having; thus described my invention, I claim as new and dpsi re tosecure by Letters Patent- 1. The combination of a base plate or frame, ahinged and spring-cushioned supportingplate, a clamping device hinged tothe baseframe and bent at its upper part so as to extend over the headof the supporting-plate, and arms attached to the supporting-plate an dadapted to engage said clamp, so as to oscillate it when thesupporting-plate is depressed, substantially as set forth.

2. The combination of a base plate or frame, a hinged andspring-cushioned supportingplate applied to said base-plate, a clampingdevice hinged to the base-plate and provided With a bent upper partextending over the head of the supporting-plate and with shanks havingforwardly-bent lower portions, and of arms attached to thesupporting-plate and adapted to engage the shanks of the clampingdevice, substantially as set forth.

In testimony that I claim the foregoing as myinvention I have signed myname'in presence of two subscribing Witnesses.

BERNHARD PETSCHE.
